ADJUSTABLE HINGE Filed oct. 10, 1950 Rober @Polso/z Mami '25 ATTORNEYSPatented Nov. 3, 1953 UNITED STATE TENT OFFICE This invention relates ingeneral to improvements in a double-acting spring hinge and checkassembly for swing doors.

One object of the invention is to provide novel mounts for the upper andlower vertical pivots or spindles of the hinge assembly; such mountsbeing arranged to permit the spindles-by easy and convenientmanipulation of readily accessible parts-to project said spindles forplacement of the door inthe door opening in hinged Working position, orto retract the spindles to remove the door.

Another object of the invention is to provide a hinge assembly for swingdoors, which includes a double-acting, spring actuated closure, andcheck mechanism of novel construction and function.

A further object of the invention is to provide a hinge assembly, forswing doors, which is simple to install and adjust after installation.

An additional object of the invention is to provide a hinge assembly,for the purpose described, which is designed for ease and economy ofmanufacture.

Still another object of the invention is to provide a practical andreliable hinge assembly for swing doors, and yet one which will beexceedingly effective for the purpose for which it is designed.

These objects are yaccomplished by means of such structure and relativearrangement of parts as will fully appear by a perusal of the followingspecication and claims.

In the drawing:

Fig. l is a foreshortened elevation of a door mounted by means of theimproved hinge assembly; the upper and lower spindle mounts being insection.

Fig. 2 is a cross section on line 2-2 of Fig. l.

Fig. 3 is a plan View, partly broken away, of the spring actuatedclosure mechanism.

Fig. 4 is a sectional elevation of said closure mechanism, as in use.

Referring now more particularly to the characters of reference on thedrawing, the improved hinge assembly is adapted for use in connectionwith a swing door, indicated generally at I, adapted to be mounted forto and fro swinging movement in a door frame which includes a door jamb2 upstandingY from the floor 3, and a header 4. y Y

'I'he upper and inner corner of the door I is pivotally mounted inconnection with the header 4 as follows:

A vertical sleeve 5 is disposed in a bore formed in the door I from itsupper edge, and an upper, vertical spindle 6 is initially slidablydisposed in said sleeve 5.

The upper, Vertical spindle 6 normally projects a distance above theupper edge of the door I and engages in a matching socket 'I of a socketplate 8 secured horizontally to the under side of the header 4.

A rotary shank il extends through the door horizontally from its inneredge; such shank at its inner end being formed as a pinion I0 whichprojects into the Vertical sleeve 5 and runs in mesh with a rack IIformed on the spindle S intermediate its ends.

At its outer end the rotary shank s includes a slotted head I2 whichseats ush in a socket I3 of a plate I4 attached to said inner edge ofthe door. The shank 9 is rotatable but axially removably secured withrespect to the socket I3. By rotating the head I2 with a screw driverthe upper Vertical spindle 6 may be caused to move between a retractedand an advanced or projecting position.

When the door I is being installed, the spindle E is initially in aretracted position, and after the door is disposed in place said spindleis run out or projected, in the manner above described, to engage in thesocket l; all by the simple manipulation of the head I2 with `a screwdriver.

The above constitutes the upper spindle mount of the hinge assembly; thelower spindle mount comprising the following:

The lower spindle is indicated at I5, and is in substantially verticalalinement with the upper spindle 6; being adjustable, however, in themanner as will hereinafter appear.

The lower spindle I5 is relatively short and projects upwardly inmatching relation into a socket member Iii; there being a slot and screwarrangement I 'I exposed below the door, whereby the lower spindle I5may be held up within the socket or permitted to drop into a dependingposition, and as is necessary in connection with the mounting of thedoor in place, as hereinafter set forth.

The socket member it is exteriorly rectangular and engages in ahorizontal inverted U-shaped guide channel I8 which is recessed upwardlyinto the door I from its lower edge at the inner corner; such guidechannel including, at its outer end, a vertical attachment plate IQrecessed into the rear edge of the door.

The channel I8 and attachment plate I9 are secured in place by screws,as shown.

The socket member I6 includes an ear 2G which upstands through a slot 2|in the top of the inverted guide channel 8, and a horizontal screw rod22 is threaded through such ear, being rotatably but non-axially movablymounted in connection with said guide channel la above the same, as inan eye member '23 threaded into the web of said channel. At its outerend the screw rod 22 is formed with a slotted head 24 which is flushwith the attachment plate i9.

Upon rotation of the slotted head ZAby means of a screw driver, withresultant turning of the rod 22, the socket member I9 is caused to movein the guide channel IS, whereby to alter the distance of the spindle Ifrom the rear edge of the door. The purpose of this adjustment is ofcourse to attain true vertical ali'nement of the rear edge of the doorrelative to the door jamb 2.

The lower spindle I5 engages, when the door is in place and the spindleis lowered as previous- -ly described, in .detachable connection with ia.double-a,cting, spring .actuated .closure .mechanism, indicatedgenerally at 25, and which-lacon- .structed in detail asfollows:

The closure mechanism 2.5 comprisesa V,top plate 25 which overlies lanopening .3.1 precut in ythe floor below the lower .inner corner .of thedoor I; said plate being secured to the floor .by screws, as shown,randto the door jamb 2 through the medium of upstanding Y.ears 2,8 screwedto said jamb.

A .case 29 is fixed in .connection `with the top plate .26 .and .depends.through the floor .opening 21, and a vertical axis rotor 39 isdisposedin .such

case; said rotor including .a lower vtrunnion 3! and an Vupper trunnion32 journaled Vin the bot- .tom ofthe case and insaid plate 25,respectively.

rEhe trunnion .3L-2 is formed with an upwardly opening socket 33 `intowhich the .lowerfspindle l5 normally seats; .saidspmdle and ,socket.being of 4matching nonpcircular .configuration whereby when .thedoor vlswings one way `or theothercorresponding part-circle rotation isimparted to .the :rotor Nlill. The lower spindle l5 .isadjnsted.downwardly Vby the slot and screw `arrangement Il so `that suchspindleseats in the .socket 3,3, .as aforesaid.

The rotor 3d is formed with a horizontal .cross bore .34 at .rightangles to .the .closed .position of the door` l, and opposed .plnng-ers35 project Linto -the `cross bore .3A from opposite ends; Ysuch plungersbeing socketedat Atheir .inner .end portions and telescopic, having aheavy-.duty cornpression spring 3.6 engaged inthe socketed portionsof-said telescoped plungers to `urge the latter apart.

At their outer ends the opposed .plungers 35 are each formed witha fork.3.1, .which orkstraddles a horizontal elliptical .track 38' formed inthe case 29 about the vertical walls thereof.

Rollers ,39 are journaled in the forks 31 Vand ride the inner edge .ofsaid Yelliptical track 3 8.. AS the forks 3l' straddle the track 38 therollers 39 are always maintained in proper ,engagement lwith said track,without the necessity of any keyway or guide means ,between the plungers35 and lthe rotor 36.

The major axis of the elliptical track 38 is parallel to the normalposition of the door l so that under the action of the spring 2G theopposed plungers 35 normally seek the position shown in Fig. 3, wherebyto maintain the `swing door I in its closed position. However, `uponopening of said swing door l 90 in either direction from its closedposition, the rollers 39 snapengage into notches 4l] at opposite ends ofthe elliptical track 38, thereby releasably holding the door in an openposition.

With the above described hinge assembly a swing door may be readilyinitially installed in place or subsequently easily removed; the doorwhen in place being under the effective control of the double-actingspring actuated closure mechanism. While the mounts for vthe upper andlower spindles 5 and I5, respectively, are of simplie fied structure,they nevertheless provide for iq-uick adjustment of said spindlesbetween a re- Ttracted position which permits the door to be removed,and an advanced or projected position withthedoor then subject to thecontrol of the mechanismzi From the foregoing description it will bereadily seen tthat there has been produced such a device assubstantially fullls the objects of the invention, .asset forth herein.

While .this `specification-sets forth in detail the present andpreferred construction .of thedevce -stillin practice suchdezviationsfrom such detail `may .be resorted .to as .do not form .a departure from.the spirit of the invention, v.as dened by .the appended .claims.
